to the root hash through that and sister branches to be recomputed. What we have described is in fact the “Merkle” part of the tree, the “Patricia” part comes from the way keys are located in the tree. Patricia trees are tries11 where any node that is an only child is merged with its parent. They are also known as “radix trees” or “compact prefix trees”. A trie is a tree structure that uses prefixes of the keys to decide where to put each node. The Merkle Patricia Trees implemented in Ethereum have other optimizations that overcome inef- ficiencies inherent to the simple description presented here. Figure 2.3: Simplified Merkle Patricia Tree For our purposes, the Merkle aspect of the trees is what matters in Ethereum. Rather than keeping the whole tree inside a block, the hash of its root node is embedded in the block. If some malicious node were to tamper with the state of the blockchain, it would become evident as soon as other nodes computed the hash of the root node using the tampered data. The resulting hash would simply not match with the one recorded in the block. At this point we should find ourselves asking a big question: why not simply take the hash of the data? Merkle Patricia Trees are used in 11 https://en.wikipedia.org/wiki/Trie 33PDF Image | Intro to Ethereum and Smart Contracts
